Title: Improved method and apparatus for measuring the rate of flow of fluids and detecting leaks in the sheaths of electric cables
Inventor: HOOKER ERIC JOHN
IPC: G01M3/28
Filed: 1955-07-06
Abstract: 800,005. Measuring flow rate. SOUTHERN UNITED TELEPHONE CABLES, Ltd. July 6, 1956 [July 6, 1955], No. 19535/55. Class 69(1). A system for measuring low rates of flow of fluid comprises a flow-meter, a fine control valve, a connection between the inlet side of the meter and a source of fluid pressure, a connection between the outlet side of the meter and the fine control valve, the outlet of which is open to the atmosphere or is connected to a low pressure part of the system and a connection between the outlet side of the meter and a receiver. As shown applied to apparatus for finding the position of a leak in a sheathed cable, high-pressure gas from a cylinder 1 is passed through an air filter 2, a pressure regulator 3 and a main stopcock 4 to a cable 5. Two Rotameters R and R2 are connected in parallel across the stop-cock 4 and a stop-cock 9 followed by a Rotameter R3 and a fine control valve 10 are connected to a branch in the line from the main stop-cock to the cable. An apparatus as above is connected to each end of a cable which is leaking and when a steady state has been reached at both ends of the cable, the cock 9 and fine control valve 10 are adjusted to give a clear reading on Rotameter R3. The required flow rate is the difference between the readings of Rotameters R2 and R3. Rotameter R1 has a different scale range from that of R2 and is used if the conditions are more suitable to the use of that scale. The distance of the leak from either end of the cable may be calculated from the flow rates. Rotameter R3 may be dispensed with, the fine control valve being set to a predetermined flow rate and the difference between that flow and the flow shown by R2 with the cable in the circuit giving the required flow rate.

Patent GB-652328-A (GB)
Title: Preparation of iodoanthanthrones
IPC: C09B3/66
Filed: 1948-07-21
Abstract: Iodoanthanthrones are made by heating anthanthrone or a substitution product thereof, or an intermediate yielding anthanthrone or its substitution products under the conditions of the reaction, e.g. a 1,11-dinaphthyl-8,81-dicarboxylic acid, with iodine or an iodine-yielding reagent in oleum, the reaction being carried out in a closed vessel at a temperature of 110-150 DEG  C. and at a pressure at least equal to the pressure autogenously produced by the reaction mixture.  The oleum preferably contains 1-12 per cent sulphur trioxide, and the quantity of anthanthrone compound is preferably 8-10 per cent of the amount of oleum.  The duration of the reaction may be 5-20 hours, and the pressure may rise to 6.5 atmospheres. Simultaneous bromination may be effected.  In examples: (1) anthanthrone itself and 1,11 - dinaphthyl-8,81-dicarboxylic acid are each simultaneously brominated and iodinated, in oleum in a closed vessel to give the same product, viz. an iodobromanthanthrone which dyes cotton scarlet shades; (2) anthanthrone is iodinated as under (1) to give a diiodoanthanthrone dyeing cotton violet p  shades. Bromoiodide may be used instead of a mixture of bromine and iodine.
Patent GB-813886-A (GB)
Title: A device for transferring code signals from a tape to a register, and a converter using such a device
IPC: G06K7/00
Filed: 1957-06-21
Abstract: 813,886. Tape to card converters. STANDARD TELEPHONES & CABLES Ltd. June 21, 1957 [June 27, 1956], No. 19579/57. Class 106 (1). In a converter for transferring data from magnetic tape to perforated cards the tape has two tracks, one containing code signals arranged in a serial order and the other has clock pulse signals corresponding to the bit positions of the code, the clock pulses being fed to an electronic counter with a step for each bit position of the code which control a group of gates, one for each bit position, the code bits being passed by the gates to a register having a cell appropriated to each bit position of the code. A matrix of relay contacts converts the stored signals to a different code. In the form described, a four-bit binary code is used, the bits being serially recorded in track 7 while track 6 contains the clock pulse signals. Head 10 reading track 6 passes the clock pulses to the counter TRC comprising a ring of four triggers, each of which is connected to an AND gate 16. These are connected to corresponding ones of the cells of register TRE. Reading head 12 passes the data code pulses through gate 15 (opened by clock pulses) to each of the gates 16. These gates, opened in turn by the counter TRC pass the data signals to the register TRE. The cells of register TRE are coupled in turn to cells of a similar register TRS through AND gates 17 and these are connected to operate relays S1, S2, S4 and S8 controlling the contacts of a decoding network converting the binary coded data to decimal notation. Operation.-The clock pulses are also passed to gate 20 so that when the fourth stage of counter TRC is set a pulse passes through cathode follower V3A to multivibrator 22 and gates 17. By a similar arrangement a clock pulse is passed to multivibrator 22 when the third stage of the counter is set. The multivibrator introduces a time lag so that the gates 17 have allowed the contents of the first register to pass to the second register before the first register is reset by the multivibrator signal over line 23. The pulse from cathode follower V3A also passes to gates 24, 25 which in turn apply pulses to the multivibrator 26 controlling an interlock relay 27 governing contact 28 to connect the contact network to the " odd " or " even " lines. The data set up in the network 18 controls the card punch magnets. The clock pulse passing to multivibrator 22 when the third counter stage is set causes a resetting pulse to pass to the second register over line 29. The interlock relay operates after each unit of data has been read from the tape (i.e. when counter TRC reaches the fourth stage) to switch the contact 28 to the energized line to energize the punch magnets and cause the value set up in the network 18 to be punched in the card. The odd and even lines are energized in turn by a switch on the punching machine.

Title: Improvements in or relating to the production of foamed polyester-polyisocyanate products
IPC: C08J9/00
Filed: 1955-07-07
Abstract: Foamed polyester-polyisocyanate resins are made by cooling a polyester having dispersed within it water necessary for the subsequent formation of carbon dioxide to a temperature below that at which carbon dioxide is subsequently evolved, mixing said polyester at said temperature with a separately cooled polyisocyanate and subjecting the mixture to a temperature high enough to effect said reaction.  The specified polyester is derived from ethylene glycol and adipic acid and may be modified by a small proportion of a bi-functional amino compound, e.g. monoethanolamine and ethylene diamine.  Specified polyisocyanates are toluene- 2 : 4 - diisocyanate and toluene - 2 : 6 - diisocyanate.  Suitable catalysts for the reaction are the N-alkyl substituted morpholines, e.g. N-methyl morpholine. Dispensing agents specified are the alkylene oxide derivatives of long chain fatty acids.  In the examples, a mixture of a polyester derived from ethylene glycol and adipic acid, N-methyl morpholine, water and a dispensing agent is mixed with toluene-2 : 4-diisocyanate at a temperature of: (I) - 50 DEG  F; (II) - 10 DEG F.; (III) - 50 DEG  C.; (IV) - 10 DEG  F.

Filed: 1924-08-19
Abstract: 242,726. Igranic Electric Co., Ltd., and Tubbs, C. F. Aug. 19, 1924. Automatic c i r c u i t - breakers, tripped to open by the movement of a bimetallic member 1, are adjusted to operate at any desired temperature of the member 1 by two devices, such as screws 12, 14, which determine the position of a plate 11 which bears at 10 against the member 1. The member is V-shaped and may be surrounded by a heating coil and the screw 12, which is mounted in a frame 13 by means of a ball joint, is turned by a pointer 15 which moves over a scale which may be calibrated in percentages of overload. The screw 41 is used for coarse adjustment or zero setting. When the current reaches a strengtth corresponding to the predetermined overload, the end 9<a> of the bimetallic member 1 moves to the left and releases a spring-controlled bell-crank lever 9, 6 carrying a contact 5, which thereupon moves away from a contact 4. The device is re-set by a push-button 17. To compensate for variations of atmospheric temperature a second bimetallic strip 19, Fig. 6, may be mounted on the opposite side of the panel 3 and connected by a pin 20 to the strip 1. The strips act in opposition and so do not move for variations of temperature which affect both equally.
